Two New Coordination Polymers Assembled with a Functionalized Ligand:Syntheses and Crystal Structures

         

摘要

Two new transition-metal organic coordination polymers [M(mna)2](M = Cd(1),Zn(2);mna = 2-mercaptonicotinic anion) have been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction along with IR and elemental analyses.Compound 1 is generally a one-dimensional linear structure bridged through the sulfur donor of mna ligand,while 2 is a one-dimensional zigzag chain ligated via the oxygen donor of mna ligand.These compounds further result in three-dimensional structures via intermolecular π...π stacking interactions and/or hydrogen bonding interactions.The two compounds were structurally determined by single-crystal X-ray diffraction.Complex 1 crystallizes in monoclinic space group P21/c with a = 3.730(3),b = 13.973(12),c = 12.380(11) ,β = 97.953(18)°,V = 639.0(10) 3,Z = 2,CdC12H8O4N2S2,Mr = 420.72,Dc = 2.187 g/cm3,F(000) = 412,Rint = 0.0252,T = 293(2) K,μ = 2.052 mm?1,the final R = 0.0269 and wR = 0.0586 for 1377 observed reflections with I 2σ(I).Complex 2 belongs to monoclinic space group P21/c with a = 13.376(2),b = 12.8429(14),c = 7.4856(10) ,β = 96.190(10)°,V = 1278.5(3) 3,Z = 4,ZnC12H8O4N2S2,Mr = 373.69,Dc = 1.941 g/cm3,F(000) = 752,Rint = 0.0414,T = 293(2) K,μ = 2.264 mm?1,the final R = 0.0418 and wR = 0.0966 for 2396 observed reflections with I 2σ(I).
